beams of railway curs, and has reference more particularly to a new and improved means for mounting and securing the head on the end of the brake beam in it nut'nner to effect con ipurz tively fine angular adj ustments of the head re lively to the beam so as to cause the brake shoe to evenly engage the trend of the wheel, whereby to effect on application of the wearing surface oi the shoe to the wheel throughout the entire extent ol the iuce of The shoe when the brakes are applied, and secure the uniform end even wearing sway of the shoe. Our invention, in one practical form inv which the some may be mulmdiorl, is illustrated in the uccompnnyiug drawings, in which, 7

Figure l. is a. Sill!) elevations] view of the brake head shown us applied to the end of the brake boning Fig. 2 is it top plan view of the parts shown in Fig. 1; Fig. 3 is n longitudinal section through the brzilce head, showing the end of the brake beam in cross-sedtion on the line 33 of .1; Fig. l is on end view or the brake head as mounted on the end of the brskebearn; and Fig. 5 is a sectional elevation on the line 5-5 of Fig. 3. Referring to the drawings, 6 may designate the brake bezini proper and 7 the truss-bur oi the usual type of trussed broke bcdm, wherein the ends of the beam said wing being provided with s scries oi holes or ziper tin-es ind icuted at I ll. The broke heed-is provided with n control circular transverse hub 13 that is jOlLlIlillGd on the rounded bearing surface oi the bearing member 8; and said build: head is further provided with a. pair of rigid laterally ii-directing wings l l lying substantially in the planes of the sides of the head. The wings 14 of the hendnre each provided with a series of registering ztpcrtures 1-5 dil'l'crently groupedrelatively to the series oi holes 12 in the wing it). Outhe squared 'projet-ting end 1}; (Fig. T1) of the bearing member 8 is snugly fitted an outer wins; 10 provided with a. series of apertures l2 registering with the corresponding apertures in the inner wing 10 that is rigid with the broke-beam; and said outer wing may be conveniently secured in place in a. removable manner by s cotter-pin l7 psssed through registering holes in the hub of the wing and the end portions 16 of the bearing member. It will thus be seen that we provide on the end of the brake beam and lying adjacent to the two sides of the brake heed u pair of prrullcl laterally projecting wings 10 lutving a series of registering apertures, and we also provide on the back of the head, rigid and preferably cast integral therewith, 2'. corresponding pair of wings l4 provided with registering apertures that are differcntl y grouped or arranged relatively to the apertures oi the wings 10, so that by slight angular adjustments of the head on its bearing one or more pair of registering holes of the Wings 14 is brought into registration with one or more pair of registering holes in the Wings 10; so thut, by inserting u cotter-pin 18 through said registering holes the head is rigid secured relatively to the beam in any onguhnzposition of adjustment suitable to effect a proper and correct bearing of the brake shoe ripen the wheel. The grouping of the respective series of holes carried by the wings 10 and Li is somewhat upon the principle of the Vernier scale, which secures the nutximum number of possible adjustments of the head within the outside limits of angular movement which the broke-head may have in service. h

19 indicates the usual transverse bearing in the upper side ol the hood designed to receive the usual pin'or bolt (not shown) of the hunger; and it will be readily understood by those skilled in the art that the angular adjustment of the head on the beam depends principally upon the height at which the brake head is supported relatively to the wheel.

It will thus be seen that the device of our invention provides a simple, easily manipulated, and finely adjustsble means for mounting and securing a brake head upon it broke beam with capacity for angular adjustment for the purpose as described.

Minor variations nnd modifications of thestruc ture shown and described will readily suggest themselves to those skilled in the art, andhcnce we do riot'limit the invention to the precise mechanism disclosed, except to the extent indicated in specific claims.

i We claim. I

1. The combination with n brnkebeum having a bearing llll ,wings at various positions of angular said wings at various positions of relative angular adjust on its end, of n brake-head rotatably mounted on said bearing, said brake-head having a pair of rigid, laterally projecting apertured wings substantially in the planes of the sides of the head, and a cooperating pair of laterally projecting wings rigid with said brake-beam and lying, alongside said wings of the head, said brake-beam wings having registering apertures differently arranged relatively to the apertures of the wings of the head, and a pin adapt ed to be passed through registering holes in said pairs of adjustment of the head, substantially as described.

4.The combination with a brake-beam, of a collar fast thereon, a bearing member secured on the end of the beam and having a laterally projecting wing abutting against i l l said collar, 11 brakehead rotatably mounted on said hearing member and having one or more lutemjlly projecting Wings. and awiug (letachahly secured to the projecting end 0isaid bearingmember opposite the end of the brakeheam, all of said wings lying side by side and the wings of said hearing member and head having differentlygrouped series of holes, respectively, and a pin adapted to be passed through registering holes in all of said wings whereby the head may be secured at various angular-1y adjusted positions on the brake-beam, substantially as described CARL E.
